PIPE-SUPPORTING HANGER.

SPECIFICATION forming part of Letters Patent No. 247,361, dated September 20, 1881.

Application filed June 29, 1881. (No model.)

To all whom it may concern 'Be it known that I, WILLIAM KANE, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented an Improved Pipe-Supporting Hanger, of which the following is a specification.

My invention consists of a hanger, fully described hereinafter, for suspendingsteam-heating pipes from beams or rafters, the objects of my invention being to afford facilities for the vertical adjustment of a series of such pipes, and for permitting the same to freely expand and contract without disturbing the fastenin gs of the'hanger.

In the accompanying drawings, Figure 1 is a perspective View of my improved hanger for steam-heating pipes; Fig. 2, a vertical section of the same; and Fig. 3 a view showing the mode of securing the hanger to the side of the beam.

It should be remarked, in the firstinstance, that insurance companies have recently objected to the usual plan ofseeuring steam-heating pipes to the walls and partitions of factories, as frequent fires have been due to the placing of greasy rags and other combustible materials on or nearsuch pipes, and these objections have induced the owners of factories and other buildings to suspend the pipes from rafters or beams, a plan which can be easily carried into effect by the aid of my invention, which I will now proceed to describe.

A plate, A, is provided with openings to a,

for the admission of bolts or screws, by which the said plate may be secured to the under side of a beam or rafter, B, as shown in Fig. 2, or to the side of a beam, as shown in Fig. 3. The upper end of a link, D, is hinged to lugs b b on the plate A, the lower end of the link being yoke-shaped so as to admit a nut, 61, to which is adapted the upper threaded end of a rod, G, the latter passing freely through the lower end of the link, the lower threaded end of the rod passing freely through a cross-bar, H, and being screwed into a nut, e, beneath the same. There are on the upper edge of the cross-bar projections h, the bar being arranged, in the present instance, for supporting four sections ofsteam-heatin g pipes, f, and the projections being such as to permit a limited lateral movement of the pipes, but preventing themfrom crowdingagainst each other, and preventing the outer sections from escaping from the bar.

As the beams of a floor are more or less uneven it is important that, after a series of the plates A have been secured to their places either beneath or on the sides of the beams, means should be provided for the vertical adjustment of the cross-bar H, so that the pipes may be level. This adjustment may be made by turning thelower nut, e, of a rod, G, hinged directly to the plate A, without the intervention of a link, D; but I much prefer the use of the link and of-a rod which has a right-handed screw-thread at one end and a left-handed screw-thread at the other end, so that the operative engaged in laying the pipes can readily grasp the rod and turn it in either direction, as the desired adjustment of the cross-bar may suggest. I prefer to make the 1011 G of a piece of pipe similar to those laid on the cross-bar, as the workmen have at hand facilities for threading such pipes.

The nuts d and 6 may be dispensed with, and the rod maybe screwed at one end directly into the link, and at the other end into the cross-bar, but the use of nuts is to be preferred.

One object of hinging the hangerto the plate A is to insure its suspension in a perpendicular position in the first instance, another object being to permit the crossbar to yield to the longitudinal expansion and contraction of the pipes under different degrees of tempera ture, so that the fastening of the plate A will not be strained by such expansion and contraction of the pipes.

I claim as my invention 1. The combination of theplate A,constrncted for attachment to abeam or rafter, the supporting-rod pivoted to the said plate, the crossbar, and the steam-heating pipes, all substantially as set forth.

2. The combination of the plate A, adapted to be secured to the beam or rafter, the vertically-adjustable cross-bar H, and the hinged connecting-rod, all substantially as set forth.

3. The combination of the plate A, the link D, hinged to the said plate, the cross-bar H, and the rod G, connected to the cross-bar and link through the medium of right and left handed screw threads, all substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM KANE.
